ANDREW VACAREZZA, 0F VINELAND, NEW JERSEY.

RATCHET-WRENCH.

To all whom it may concern Be it known that I, ANDREW VACAREZZA, acitizen of the United States, residing at Vineland, in the county ofCumberland and State of New Jersey, have invented certain new and usefulImprovements in Ratchet- Trenches, of which the following is aspecification.

My invention relates to improvements in ratchet wrenches, the object ofthe invention being to provide an improved device of this characterwhich can be operated to screw a nut into place or remove the same, andwhich, in combination with various attachments may be used on varioussizes and shapes of nuts.

A further object is to provide improved means for mounting the nutengaging member within the handle or operating arm, and provide improvedmeans for adjusting the pressure of the spring pawl against the teeth ofthe nut engaging member.

With these and other objects in View, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaim.

In the accompanying drawings: Figure 1 is a plan view illustrating oneform of my improvements. Fig. 2 is a view in side elevation. Fig. 3 is aview in longitudinal section. Fig. 4. is a plan view with the coveringplate removed. Fig. 5 is a view in elevation illustrating myimprovements in connection with a brace. Fig. 6 is an enlarged plan viewof the arm carrying the nut engaging member. Fig. 7 is a view inlongitudinal section through the center of Fig. 6. Fig. 8 is a plan viewof the arm 20 with the top plate 24: removed, and Fig. 9 is aperspective view illustrating an attachment.

My improved wrench comprises a handle 1 having a covering plate 2.removably secured thereto by screws 3, the latter projected throughopenings in plate 2, and screwed into threaded openings 4: in handle 1.The handle 1 and plate 2 at one end are enlarged and circular in form asclearly shown. This circular enlargement of the handle forms a chamber 5in which a rotatable member 6 is mounted. This member 6 is of greaterlength than the thickness of the handle and extends through a circularSpecification of Letters Patent.

opening 7 in handle 1 and through a ring 8 which is screwed into athreaded opening 9 in plate 2.

An annular series of teeth 10 are formed on member 6, said teeth locatedwithin the chamber andvwhen the ring 8 is removed, the member 6 may bedrawn through the opening 9. This ring 8 has an angular flange 11 at itsouter end, so that it may be readily turned by an ordinary wrench, andas the teeth 10 are located midway between the ends of the member 6, thelatter is alike at both ends, and may be placed within the deviceindiscriminately.

The teeth 10 are engaged by a spring pawl 12, one end of which ispositioned in a recess 13 in an enlargement 14 integral with handle 1. Ascrew 15 projects through a threaded opening 16 in an enlargement 17 onthe handle 1 and bears against the spring pawl 12 between the ends ofthe latter, so that by adjusting this screw 15, the spring tension ofthe pawl against the teeth may be regulated to suit conditions.

The member 6 has an angular opening 18 to engage a nut, and when inposition on a nut the oscillation of handle 1 will cause the nut to bescrewed into place or removed. Byreversing the handle, the nut may bescrewed either way.

In the modification of my improvements illustrated in Figs. 5 to 8inclusive, I support my improved rotatable member 19 corresponding tomember 6 in an arm 20 which constitutes a part of an ordinary brace 21.This arm 20 is provided with a ring 8 which holds the rotatable memberin operative position, and the spring pawl 12 is adjusted by means ofthe screw 15 as in the form first described.

As the arm 20 is not reversible, it is necessary to lock the rotatablemember when unscrewing a nut. To do this I provide a pivoted catch 22which is adapted to be moved into any of a series of notches 23 in themember 19, and hold the latter againstturn- 100 ing. This arm 20 isprovided with a removable plate 24; correspondingto plate 2, andremovably secured by means of screws 25.

In Fig. 9 I illustrate in perspective my 105 improved attachment whichis provided with an angular shank portion 26 adapted to be positioned inthe angular opening 18.

To securely hold the attachment in the rotatable member, a spring 27 issecured in a recess 28 in shank 26. This spring is fixed at one end bymeans of a pin 29, but its other end is free and fiaresoutwardly so asto firmly bind against the wall of the opening and securely hold theattachment therein. The other end of the attachment is rectangular orother shape as shown at 30, and may be made of anysize and of any shapein accordance with the size and shape of the nuts on which it is to beused. 713 providing Various attachments, the wrench may be used for anyordinary purpose.

Various other slight changes might be made in the general form andarrangement of parts described without departing from my invention, andhence I do not limit myself to the precise details set forth, butconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of the appended claim.

Having thus described my invention, what projecting through the support,said nut V engaging member having an annular series of teeth, a springpawl within said hollow support, secured at one end and at its free endengaging the teeth, and a screw threaded through the wall of saidsupport and at its inner end bearing against the spring pawl between theends of the latter, whereby the tension of said pawl may be regulated,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
